Overview

Release notes

What's included?

Free trials

Smaller, faster, smarter code

Make sure your code is the best it can be. Our compiler makes it fast, effective and highly compact. And powerful code analysis ensures its quality. The compiler and the debugger of IAR Embedded Workbench are by many considered the best in the industry.

Working with safety-critical applications?

The functional safety versions of IAR Embedded Workbench are certified according to IEC 61508, the international umbrella standard for functional safety, as well as the automotive standard ISO 26262.

Latest benchmarks

We are proud of the benchmarks we get.

Outstanding speed optimizations enable IAR Embedded Workbench to generate very fast performing code. With the shortest possible execution times it is the ultimate choice for developing low-power applications.

EEMBC is a non-profit industry association for embedded microprocessor benchmarks. EEMBC CoreMark is a simple, yet sophisticated, benchmark that is designed specifically to test the functionality of a processor core. Running CoreMark produces a single-number score allowing users to make quick comparisons between processors.

Highlights in latest versions

IAR Embedded Workbench for RL78, V.3.10
Released Sept 20

Updated IDE

The IDE has new artwork, enhancements to window management and docking, customizable toolbars, revised Information Center, and new tutorials.

Enhanced Registers and Symbols windows in the C-SPY debugger

The C-SPY Symbols and Registers windows have been re-designed with new features. The Symbols window now has a filtering function and a new column displaying to which program module a certain symbol belongs. Some of the new features in the Registers window are drag-and-drop support from source code windows, detailed register tool-tip information, and improved handling of user-defined registers groups.

E2 emulator support

C-SPY now supports the Renesas E2 on-chip debugging emulator.

C-SPY start/stop function support

The start/stop function available for the OCD emulators makes it possible to execute specified routines of the user application immediately before starting and immediately after halting program execution.

Smart Analog support in C-SPY

The Timeline and Event log windows in C-SPY now supports RL78 devices with a built-in analog front-end for sensor applications.

IAR Embedded Workbench for RH850, V1.40
Released Jan 9

Performance analysis

The performance analyzer facility in the hardware debugger can measure a number of execution aspects to help you understand how well your application performs on the MCU. Because performance analysis uses the debugger’s performance measurement circuit to measure the execution time, it does not slow down the execution of your application. The performance analysis is capable of measuring these execution aspects:

the total number of executed instructions

the number of executed instructions that trigger branching

the number of accepted interrupts and other exceptions

the total number of clock cycles

the number of clock cycles, excluding the interrupt processing

the number of cycles in which DI/EI interrupts are disabled

the number of instruction fetch requests, and instruction cache non-wait responses for instruction fetch requests, issued by the IFU

the number of flash ROM data requests.

The analysis can cover either the entire execution or execution between two breakpoints. Performance analysis settings cannot be changed during the execution and the results of the analysis are displayed in the Performance Analysis window.

Interrupt logging

Interrupt logging provides you with comprehensive information about the interrupt events. This might be useful for example, to help you locate which interrupts you can fine-tune to become faster. You can log entrances and exits to and from interrupts. You can also log internal interrupt status information, such as triggered, expired, etc. In the IDE:

The logs are displayed in the Interrupt Log window

A summary is available in the Interrupt Log Summary window

The Interrupt graph in the Timeline window provides a graphical view of the interrupt events during the execution of your application.

Flash memory erase

It is now possible to erase all flash memory areas including the data flash area via the menu command Project>Download>Erase memory.

Extended functionality in C-STAT

The static analysis tool C-STAT has been extended with approximately 150 new checks including 90 new MISRA C:2012 checks and two new packages of checks. There are also new options to enable or disable the false-positives elimination phase of the analysis and to exclude files from the analysis. C-STAT message suppression can now be controlled by directives placed in comments in the source files.
